lo 3.3. what is exchanged between capillaries and the bodys cells?
lipids and proteins
carbon dioxide and oxygen
carbon dioxide and nitrogen
water and electrolytes
nutrients, oxygen, and waste products

Explanation:

Capillaries are the smallest blood vessels. They have thin walls that allow for the exchange of substances between the blood and the body's cells. Nutrients (such as glucose, amino acids) and oxygen are delivered from the capillaries to the cells. At the same time, waste products (like carbon dioxide) produced by the cells are transferred into the capillaries to be carried away. Lipids and proteins are not the main substances exchanged in this general context. Carbon dioxide and oxygen are part of the exchange but do not cover all substances. Carbon dioxide and nitrogen - nitrogen is not a major substance in this exchange. Water and electrolytes are also part of the overall exchange but again, the most comprehensive answer is nutrients, oxygen, and waste products.

Answer:

Nutrients, oxygen, and waste products
